surface area of a sphere formula: A=4πr^2
314=4 x 3.14 x r^2 => r=5
It's B
Answer:
#8 - substitution property of equality
hop this helps! <3
I’m pretty sure it’s B. But I could be wrong.
Step-by-step explanation:
1 face area = length x width (aka length x length since cube)
therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)
volume = length x width x height = 12 x 12 x 12 = 1728cm^3
